CrystalView Optical Glass
CrystalView optical glass lenses provide superior clarity, color, and transmission of light over standard glass lenses used by the competition. Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA’s CrystalView lenses transmit up to 95% of available light to the diver for clear crisp vision.  CrystalView lenses are used in all PRO models masks. Read more
